Based on my experience, for a manually operated zip trak of that size I'd budget for about $2K, give or take. I couldn't see the measurements on my quote / invoice, but I think mine are a similar size.
I think the material I have on my blinds is called Visiontex Plus Suncreen. Basically its a woven synthetic material that is still able to sinificantly cut down the UV and heat, allows me to see out while providing some level of privacy, as well as providing some airflow. EDIT - Looking at @jchurch 's earlier post, the pic from their website looks very similar to what you see from the outside with the fabric I chose.
As I said, mine are manually operated (at the moment), they also have a fully enclosed hood around the roller, the locking mechanism at the bottom of the track. The ability to withstand strong winds was also a consideration for me.
I hope this provides some valuable information for you. As happy as I am with my purchase, I can't say I did extensive research to work out the best value for money option available at the time. I had used the company who installed the blinds before and was happy with their products and service, so I didn't look too hard for any alternatives.
